hypolipidaemic effect of acanthophora spicifera (red alga) and cystoseira trinode (brown alga) on albino rats

Hypolipidaemic Effect of Acanthophora Spicifera (red Alga) and Cystoseira Trinode (brown Alga) on Albino Rats

The polysaccharides of Acanthophora spicifera and Cystoseira trinode were isolated and their components identified using different chemical and spectral techniques. Their effects were evaluated for the first time on hyperlipidemic rats. Atorvastatin Ca (Lipitor) was used as a reference drug. Results revealed that the polysaccharides isolated were of sulfate type. Acanthophora spicifera lowered ...

Cytotoxic hydroazulene diterpenes from the brown alga Cystoseira myrica.

Cytotoxicity-guided fractionation of the alcohol extract of the brown alga, Cystoseira myrica, afforded four new cytotoxic hydroazulene diterpenes, dictyone acetate (2), dictyol F monoacetate (4), isodictytriol monoacetate (6), and cystoseirol monoacetate (8), together with two known cytotoxic hydroazulene diterpenes, pachydictyol A (1) and dictyone (3). The constitution of each isolated compou...

Antiherpes virus effect of the red marine alga Polysiphonia denudata.

The water extract from the red marine alga Polysiphonia denudata (Dillwyn) Kutz. from the Bulgarian Black Sea coast selectively inhibited the reproduction of herpes virus type 1 and type 2 in cell cultures (EC50=8.7 to 47.7 mg/ml) as shown by the reduction of virus-induced cytopathic effect and viral infectivity. The virus-inhibitory effect was dose-related, strain-specific and depended on viru...

Diterpenes from the Brown Alga Dictyota crenulata.

The crude extract of the Brazilian brown alga Dictyota crenulata was analyzed by NMR spectroscopy and HRGC-MS techniques. Seven diterpenes were identified: pachydictyol A, dictyodial, 4beta-hydroxydictyodial A, 4beta-acetoxydictyodial A, isopachydictyol A, dictyol C and dictyotadiol. Xeniane diterpenes have previously been found in D. crenulata from the Pacific Ocean. The results characterize D...

Genome of the red alga Porphyridium purpureum

The limited knowledge we have about red algal genomes comes from the highly specialized extremophiles, Cyanidiophyceae. Here, we describe the first genome sequence from a mesophilic, unicellular red alga, Porphyridium purpureum. The 8,355 predicted genes in P. purpureum, hundreds of which are likely to be implicated in a history of horizontal gene transfer, reside in a genome of 19.7 Mbp with 2...
